Its name comes from the Arabic ibt al jauzah, meaning 'armpit of the central one'. It is particular bright and prominent star (the ninth brightest in the sky) and shines with a red-orange light.

It is possible that Betelgeuse will become a supernova which will be the brightest ever recorded, outshining Luna in Earth's night sky. Considering its size and age of 8.5 million years, old for its size class, it may explode within the next thousand years. Since its rotational axis is not toward the Earth, Betelgeuse's supernova will not cause a [[ | It is possible that Betelgeuse will become a supernova which will be the brightest ever recorded, outshining Luna in Earth's night sky.

NIn recent years, the star has shrunk 15% since 2403 with an increasing rate. The average speed at which the radius of the star is shrinking over the last 15 years is approximately 210–219 m/s (470–490 mph). | NIn recent years, the star has shrunk 15% since 2403 with an increasing rate.
